How to Tell If Your Gutters Are Leaking (and What to Do Next)

Jun 27, 2025

A quiet drip along the eaves may look harmless, yet that escaped water can work its way behind siding, erode soil around the foundation, and stain brick. In Oklahoma’s storm-heavy springs and leaf-filled autumns, residential gutters carry more than their share of runoff. Knowing the first warning signs of a leak keeps the problem small—and your home protected.


Why Leaks Happen

  • Loose fasteners — Expansion and contraction from hot summers and freezing snaps widen old nail holes.
  • Failed seams — Older sectional gutters separate over time, leaving a hairline gap for water.
  • Clog-driven overflow — Leaves, shingle grit, and red Oklahoma clay settle inside, forcing water over the edge.
  • Hidden rust or hail dings — Tiny pits invite slow corrosion that eventually eats through the metal.

Telltale Signs Your Gutters Are Leaking

  1. Damp lines on the fascia after a rain
  2. Pin-sized streams shooting from the underside of the trough
  3. Water marks on exterior walls below a joint
  4. Mulch displacement right under an elbow or end cap
  5. Basement mustiness within 24 hours of a storm—often the final clue water traveled down the wall

Quick Weekend Checks

  1. Walk the perimeter after the next rain. Look and listen for drips or fine sprays.
  2. Tap seams with a gloved hand. A hollow sound can signal a gap behind the joint.
  3. Inspect the ground. Soft spots or washed-out flower-bed soil trace back to a leak above.

Safety tip: Use a sturdy ladder on level ground and keep a spotter nearby. Oklahoma winds rise fast.


Simple Fixes You Can Handle

  • Clear debris first. Many “leaks” vanish after a thorough clean-out.
  • Apply gutter sealant inside clean, dry seams. Press seams together for a snug fit as the sealant skins over.
  • Pop in a new hanger. If the trough pulled away from the fascia, a screw-in hanger restores pitch.

When It’s Time for Professional Repair or Replacement

If the metal feels thin, seams have opened in several spots, or sections sag beyond easy re-pitching, a fresh seamless run often costs less long-term than repeated patchwork. Seamless aluminum or steel gutters formed on-site eliminate mid-span joints, reducing the failure points that Oklahoma hail and temperature swings exploit.


Inspection Timeline for Oklahoma Homes

  • Early Spring: Remove winter debris and seal minor splits — prepares gutters for heavy storm runoff.
  • Mid-Summer: Verify fasteners and slope after heat expansion — keeps flow steady during peak downpours.
  • Early Fall: Clear leaves before the first cold front — prevents ice dams during early freezes.
  • Post-Storm: Look for impact dents or loose elbows — hail and high winds create fresh weak spots.

Storm-Season Prep

  • Add downspout extensions or confirm underground drainage moves water at least four feet from the slab.
  • Trim back branches likely to drop twigs into the trough.
  • Schedule a quick visual check after the first major spring and autumn thunderstorms.

Wrap-Up

Spotting a leaking gutter early spares siding repairs, landscaping washouts, and foundation headaches. A slow walk around the house twice a year—plus right after Oklahoma’s big seasonal squalls—helps you catch trouble in time to handle a quick seal-and-go fix or line up a seamless replacement before small drips become costly damage.
